Server

Web-server running Apache 1.3.* or later.
DAlbum was also tested with Microsoft IIS 5 and 6.

PHP 4.1.* or later installed as CGI or as Apache Module.
Even PHP in Safe mode is
supported. PHP5 seems to be fine with the script too, but produces a few warnings that can be switched off as described in Troubleshooting section.

Image resizing tools to resize images and create thumbnails. It could be either:

Any other command-line image resizing tool. Example for NetPBM is given
here.

GD library. Please note that only GD library 2.0 or later can produce images
comparable to ImageMagick results. Please
also note that GD library above 1.6 does NOT support .GIF format. If you have .GIF
images, use ImageMagick or convert your GIFs to PNG before uploading.

None of the above. It is possible to operate DAlbum without any imaging
tools installed at all. Resized images and thumbnails shall be created and uploaded
manually in this case.

Client

In older browsers such as IE 4.0 and Opera 6, tree view is always fully expanded.
There are also minor layout artefacts with these browsers.

Finally and unfortunately, Netscape Navigator 4 is not supported - it does not seem
to understand gzip-ed pages, crashes or stops loading in the middle of the page and
does other weird stuff. Other ancient browsers such as IE 3 are also not supported.
